The sum of interior angles of a regular polygon is 1800
Find the measure of each interior angle of the polygon.

Question:

What is the measure of angle X?

The image of the measurements is attached below:

Answer:

The measure of angle x is 83°

Explanation:

Since, Vertical angles have equal measure,

Let us consider that the angle opposite to 41° is ∠y and they are equal.

i.e, ∠y = 41°

Since, the angles in a straight line add up to 180°, we have,

∠x + ∠y + 56° = 180°

Substituting the value ∠y = 41°, we have,

∠x + 41° + 56° = 180°

Adding the terms, we get,

∠x + 97° = 180°  

Subtracting both sides by 97°, we get,

∠x = 83°

Thus, the measure of ∠x is 83°

Answer:

83 degrees

Factoring the perfect square:

(7x + 6y)²

7x + 6y is a factor.

Final answer:

The correct binomial factor of the quadratic expression  [tex]49x^2 + 84xy + 36y^2 \ is \ 7x + 6y[/tex], which corresponds to option A.

Explanation:

To determine which binomial is a factor of the quadratic expression  [tex]49x^2 + 84xy + 36y^2,[/tex]we can try to factor the expression by grouping or using the factoring technique of a perfect square trinomial. On inspection, we see that 49, 84, and 36 are all multiples of 7, and also the expression resembles the square of a binomial.

The given expression can be written as:

[tex](7x)^2 + 2(7x)(6y) + (6y)^2[/tex]

This is the expanded form of the square of a binomial:

[tex](7x + 6y)^2 = 49x^2 + 84xy + 36y^2[/tex]

Hence, the factored form of the given expression is  [tex](7x + 6y)^2[/tex], which means that 7x + 6y is indeed a factor. So, the correct answer is option A.

Answer:

The diameter of the arena is 18.3 meters.

Step-by-step explanation:

        As,  14 laps = [tex]\frac{1}{2}[/tex] mile

        so, 1 lap = [tex]\frac{1}{28}[/tex] mile                               ( ∵14 × 2 = 28)

For the horse completing one lap it completes the perimeter of the circle.

            perimeter (P) =  [tex]\frac{1}{28}[/tex] mile

let diameter of that circle be represented as d,

                                  P=  [tex]\pi[/tex] × d

                            or,  [tex]\frac{1}{28}[/tex]  = [tex]\pi[/tex] × d

                            or, d= [tex]\frac{1}{28\pi }[/tex]

                              ∴ d= 18.3 meters.

The diameter of the arena is 18.3 meters.

There was a decrease of 20% in membership from October to November.

Step-by-step explanation:

Step 1; To find the percent by which the running clubs membership decreased we must find the difference between the number of members in October and the number of members in November. The number of members in the club in October was 25 whereas it reduced to 20 in the month of November.

Difference in members = Number of members in October -Number of members in November = 25 - 20 = 5

Step 2; To find the percent decrease in number of members in the running club, we divide the difference in number of members by the number of members in November . We multiply this value by 100 to get it in terms of percentage.

Percent decrease in number of members =(Difference in members / number of members in November) *100

                                                                      = (5/25) * 100 = 0.20 * 100 = 20%

So number of members in the club decreased by 20% from October to November.

Answer:

y-intercept is 1

Step-by-step explanation:

We need to find the equation of the line first.

The gradient is found using the formula:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]m=\frac{-1-2}{8--4}[/tex]

[tex]m=-\frac{1}{4}[/tex]

So the equation is y = [tex]-\frac{1}{4}[/tex]x + c

To find c we need to substitute the value of x and y into the equation:

-1 = [tex]-\frac{8}{4}[/tex] + c

-1 = -2 + c

1 = c

And c is the y-intercept so it is 1

Answer:

y- intercept = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (8, - 1) and (x₂, y₂ ) = (- 4, 2)

m = [tex]\frac{2+1}{-4-8}[/tex] = [tex]\frac{3}{-12}[/tex] = - [tex]\frac{1}{4}[/tex], thus

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, - 1), then

- 1 = - 2 + c ⇒ - 1 + 2 = 1 ← y- intercept

Answer:

a)  1 quart

b)  2 quarts

c)  33.33 % of the brown paint is made of blue paint

Step-by-step explanation:

6 quarts brown paint =  1/2 of yellow paint and 1/2 violet paint

violet paint = 1/3 red paint 2/3 blue paint

then

6 quarts brown paint =  1/2 of yellow paint and 1/2 (1/3 red paint and 2/3 blue paint)

or

6 quarts brown paint = 1/2 of yellow paint , (1/2*1/3) red paint and (1/2*2/3) blue paint

6 quarts brown paint = 1/2 of yellow paint , 1/6 red paint and 1/3 blue paint

then

a) he uses 1/6 of 6 quarts to make red paint = 1/6*6 = 1 quart

b) he uses 1/3 of 6 quarts to make red paint = 1/3*6 = 2 quarts

c) brown paint is made with 1/3 of blue paint = 33.33 % of the brown paint is made of blue paint

Doug have 30 quarters and 15 dimes.

Step-by-step explanation:

Given,

Number of coins = 45

Worth of coins = $9.00 = 9.00*100 = 900 cents

Each quarter = 25 cents

Each dime = 10 cents

Let,

x be the number of quarters

y be the number of dimes

According to given statement;

x+y=45            Eqn 1

25x+10y=900   Eqn 2

Multiplying Eqn 1 by 10

[tex]10(x+y=45)\\10x+10y=450\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](25x+10y)-(10x+10y)=900-450\\25x+10y-10x-10y=450\\15x=450[/tex]

Dividing both sides by 15

[tex]\frac{15x}{15}=\frac{450}{15}\\x=30[/tex]

Putting x=30 in Eqn 1

[tex]30+y=45\\y=45-30\\y=15[/tex]

Doug have 30 quarters and 15 dimes.

Doug has 30 quarters and 15 dimes.

Let

x = number of quarters

y = number of dimes

The total number of coins is 45. Therefore,

Total amount of the coins is $9. Therefore,

Therefore,

x + y = 45

0.25x + 0.1y = 9

0.1x + 0.1y = 4.5

0.25x + 0.1y = 9

0.15x = 4.5

x = 4.5 / 0.15

x = 30

To add or subtract linear expressions, combine like terms. For example, to add 3x + 9 and 2x + 4, you combine the x terms and the constant terms separately to get 5x + 13. The same method is applied to the rest of the problems, resulting in simplified linear expressions.

Adding and Subtracting Linear Expressions:

To add or subtract linear expressions, you combine like terms, which are terms that have the same variables raised to the same power. Let's go through the problems one by one:

Sum of 3x + 9 and 2x + 4: (3x + 2x) + (9 + 4) = 5x + 13.

Add 2n + 6 and 6n - 2: (2n + 6n) + (6 - 2) = 8n + 4.

Add -3x + 9 and 6x - 12: (-3x + 6x) + (9 - 12) = 3x - 3.

Add 1/4x + 10 and 1/2x - 7: (1/4x + 1/2x) + (10 - 7) = 3/4x + 3.

Find the difference: (3x + 5) - (2x +2) = (3x - 2x) + (5 - 2) = x + 3.

Subtract 8 from 10: 10 - 8 = 2.

Subtract 2.5x from 7.8x: 7.8x - 2.5x = 5.3x.

Subtract (3.4x + 8) from (5.8x + 10): (5.8x - 3.4x) + (10 - 8) = 2.4x + 2.

Find the difference: (8x + 5) - (2x + 8) = (8x - 2x) + (5 - 8) = 6x - 3.

Evaluate (-4x -3) - (-4x -3): (-4x + 4x) - (-3 + 3) = 0x + 0 = 0.

These are the simplified forms of the linear expressions after combining like terms.

Answer:

(b)  (x + 1 ≤ 1) ∩ (x + 1 ≥ 1) =  {x | x = 0}

Step-by-step explanation:

Here, the given expression is : {x | x = 0}

So, the ONLY element in the given set = {0}

Now, take each option and solve the given expression:

(a)  x + 1 < -1

Adding -1 BOTH sides, we get:

x + 1 -1 < -1  -1

or, x < - 2 ⇒ x = { -∞ , .... , -4,-3}

Also,   x + 1 < 1

Adding -1 BOTH sides, we get:

x + 1 -1 < 1  -1

or, x <0 ⇒ x = { -∞ , .... , -4,-3,-2,-1}

So, (x + 1 < -1) ∩ (x + 1 < 1) =  { -∞ , .... , -4,-3}∩ { -∞ , .... , -4,-3,-2,-1}  

=  { -∞ , .... , -4,-3}

⇒ (x + 1 < -1) ∩ (x + 1 < 1) ≠ {0}

Similarly, solving

(b) (x + 1 ≤ 1) ∩ (x + 1 ≥ 1)

(x + 1 ≤ 1) =  x≤ 0 =   { -∞ , .... , -4,-3,-2,-1, 0}

(x + 1 ≥ 1) =  x ≥ 0 =  {0,1,2,3,... ∞}

⇒ (x + 1 ≤ 1) ∩ (x + 1 ≥ 1) = {0}

(b)(x + 1 < 1) ∩ (x + 1 > 1)

(x + 1 < 1) =  x <  0 =   { -∞ , .... , -4,-3,-2,-1}

(x + 1 > 1) =  x  > 0 =  { 1,2,3,... ∞}

⇒ (x + 1 ≤ 1) ∩ (x + 1 ≥ 1) = Ф

Hence,  (x + 1 ≤ 1) ∩ (x + 1 ≥ 1) =  {x | x = 0}

(x + 1 ≤ 1) ∩ (x + 1 ≥ 1) =  {x | x = 0}

Answer:

 The volume of a baseball is about 13.39 cubic inches.

Step-by-step explanation:

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

7/8 x 8/3 = ?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

7 x 8

8x3

56/24

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 56 and 24 using

GCF(56,24) = 8

56/8 = 7

24/8 = 3

The fraction 7/3 is the same as 7 divided by 3

Convert to a mixed number using long division for 7 ÷ 3 = 2R1, so

Therefore:

7/3 = 2 1/3

2 1/3

The required quotient is 7/3 when 7/8 is divided by 3/8.

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.

The division operation is given in the question following as:

⇒ 7/8 ÷ 3/8

We have to determine the quotient when 7/8 is divided by 3/8

As per the given question, we have

⇒ 7/8 ÷ 3/8

⇒ (7/8) / (3/8)

Reciprocal the terms in the numerator, and we get

⇒ (7/8) × (8/3)

Apply the multiplication operation,

⇒ 56/24

Reduce the above fraction to the simplest form

⇒ 7/3

Therefore, the required quotient is 7/3 when 7/8 is divided by 3/8.
